Wondering about your setup for compiling for armhf

I am trying to compile this profiler myself from source and am running into an alignment trap issue. I was wondering what tools you are using to compile it/if you ran into something similar. Compiling with Clang 6.0.0 with -march/-mpfu options is still producing an alignment trap error, and I don't really know why. I am asking here because I can run the coz-profiler package just fine on my system, so you guys clearly know what you're doing, but when I go to run my own version it results in alignment traps. If you could provide your gcc/clang versions and/or any thoughts about what I might be doing wrong would be immensely appreciated.

Thank you in advance for any help.

Best,
Will
